I don't think it's inaccurate… system users are defined as users who can't authenticate (don't have a password, passkey, or other login credentials), don't have an email, and don't have a "Keep me logged in" token (reference) – this is all true for vanished users. Their accounts really become system users when they are vanished. We can't change this without keeping the data that the user has asked us to delete.

As far as I know, "un-vanishing" an account requires sysadmin intervention to set an email (and then perform a password reset), at which point the account is no longer a system user. Is there some other process I don't know about? (You can just rename them back and un-lock the account, but that won't let them authenticate, since the password and other credentials are removed during vanishing.)

None of this has changed recently, so I don't understand where this request is coming from. Did we start showing the "system user" status somewhere that is confusing? Where? Maybe that should have a special case for vanished accounts?
